TLV840/TLV840-Q1 Supervisors (Reset ICs) Texas Instruments TLV840/TLV840-Q1 Low-Voltage Supervisors (Reset ICs) can operate at high voltage levels while maintaining a very low quiescent current across the whole VDD and temperature range. TLV840/TLV840-Q1 offers the best combination of low power consumption, high accuracy, and low propagation delay (tp_HL = 30µs typical).
